CM1631
LCD and Camera EMI Filter
Array with ESD Protection
Product Description
The CM1631 is a family of pi−style EMI filter arrays with ESD
protection, which integrates four, six, or eight filters (C−R−C) in
a small form factor, UDFN 0.40 mm pitch package. The CM1631 has
component values of 15 pF − 100 W − 15 pF per channel with
a cut−off frequency of 120 MHz, and can be used in applications with
data rates up to 48 Mbps. The device includes ESD diodes on every
pin, that provide a very high level of protection for sensitive electronic
components against possible electrostatic discharge (ESD). The ESD
protection diodes safely dissipate ESD strikes of ±15 kV, which is well
beyond the maximum requirement of the IEC61000−4−2 international
standard. Using the MIL−STD−883 (Method 3015) specification for
Human Body Model (HBM) ESD, the pins are protected for contact
discharges greater than ±30 kV.
These devices are particularly well−suited for portable electronics
(e.g. wireless handsets, PDAs, notebook computers) because of their
small package and easy−to−use pin assignments. In particular, the
CM1631 is ideal for EMI filtering and protecting data and control lines
for the I/O data ports, LCD display and camera interface in mobile
handsets.
The CM1631 is housed in space−saving, ultra−low−profile 8−, 12−
and 16−lead UDFN packages with a 0.40 mm pitch and is available
with lead−free finishing. This smaller size UDFN package provides up
to 42% board space saving vs. the 0.50 mm pitch UDFN packages.
Features
• Four, Six and Eight Channels of EMI Filtering with Integrated
ESD Protection
• Pi−Style EMI Filters in a Capacitor−Resistor−Capacitor (C−R−C)
Network
• ±15 kV ESD Protection on Each Channel
(IEC 61000−4−2 Level 4, Contact Discharge)
• ±30 kV ESD Protection on Each Channel (HBM)
• Greater than 35 dB Attenuation (Typical) at 1 GHz
• UDFN Package with 0.40 mm Lead Pitch:
♦ 4−ch. = 8−lead UDFN
♦ 6−ch. = 12−lead UDFN
♦ 8−ch. = 16−lead UDFN
• Tiny UDFN Package Size:
♦ 8−lead: 1.70 mm x 1.35 x 0.50 mm
♦ 12−lead: 2.50 mm x 1.35 x 0.50 mm
♦ 16−lead: 3.30 mm x 1.35 x 0.50 mm
• Increased Robustness against Vertical Impacts During
Manufacturing Process
• These Devices are Pb−Free and are RoHS Compliant
